EDWARD LINDQUIST, OF OMAHA, NEBRASKA.

SLIDING-JAVI WRENCH.

Application filed January 25. 1927.

My present invention pertains to wrenches of the sliding jaw types; and it has for its object the provision of a sliding jaw wrench which while simple and inexpensive in construction and strong and durable, it is adapted to be adjusted and handled with great facility.

To the attainment of the foregoing, the invention consists'in the improvement as hereinafter described and definitely claimed.

In the accompanying drawing forming part of this specification:-

Figure 1 is a view partly in side elevation andpartly in section illustrative of the preferred embodiment of my invention.

Figure 2 is a broken View in elevation taken at right angles to Figure 1.

Figure 3 is a transverse section taken on the plane indicated by the line 33 of Figure 1.

Figure 4 is a detail perspective of the adjusting member of the wrench.

Similar numerals of reference designate corresponding parts in all the views of the drawing.

Among other elements, my novel wrench comprisesa sliding jaw 1 which within the purview of my invention may be of the shape illustrated or any desired shape. The said jaw 1 is integral with a shank 2, of rectangular cross section, and the said shank 2 at its heel end is integral with and is merged into a reduced rear portion 3 of circular cross section, by preference. The portion 3 being equipped with a thread 4 as appears in Figures 1 and 3. The jaw 1 and the parts defined as integral therewith may without affecting my invention be made of steel or of any other material suitable for wrench purposes.

In addition to the jaw 1, and the parts integral therewith, the wrench includes a body of .steel, iron or other appropriate metal or metallic alloy. The said body is formed in one piece and comprises a jaw 5 with a bore or passage 6 therethrough in which the shank 2 is sheathed, and also comprises spaced parallel longitudinal portions 7, and an intermediate portion 8 in which is a bore 9 for the reception of the portion 3 of the shank 2; said portion 8 being extended laterally in opposite directions from the plane in which the portions 7 are disposed, as appears in Figure 2.

The embodiment illustrated further com Serial No. 163,405.

prises wooden sections 10, wooden sections 11, and an adjusting member 12, the latter shown in detail in Figures 1 and 4. By particular reference to Figures 1 and 2, it will be noted that the rear portion of the longitudinal bars 7 of the wrench body are increased in width, and that the wood sections 10 and 11 are arranged at opposite sides of said comparatively wide portions of the bars 7 and are fixedly connected to said bar portions through the medium of transverse rivets 13; also, that the wood sections abut at their inner ends against and are reinforced by the intermediateenlargen 8 of the body, and that the sides of said enlargement 8 and the sides of the wood sections 10 and 11 are flush as appears in Figure 2. It will further be noted by comparison of Figures 1 and 3 that the body of the wrench recessed at 1 1, and the wood sections 11 are recessed at 15 for the reception and circular movement of the adjusting element 12.

The adjusting member 12 is formed in one piece of steel or of any appropriate metal, and is of general tubular form, the outer end of the tube being closed'as designated by 16 and being provided with a 'cent'ral minute aperture 17 through which oil may be introduced for the thorough lubrication of the threaded portion of the shank 2 of the member 12. By comparison of Figures 1 and 3 and 1, it will be understood that the member 12 is provided at its inner end with a nut portion 18 which is exteriorly of cir cular cross section and is interiorly threaded as designated by 19, and is provided at its inner end with a circular flange 20, the latter being disposed in the recess 14 of the body so that the member 12 is by the body strongly held against longitudinal movement in either direction. The nut 18 turnable about its axis in the metallic body and the wooden sections 11 of the wrench as is the tubular portion of the member 12, and at a point in the rear of and by preference slightly spaced from the metallic body and the wood section 11, the adjusting member 12 is provided with exterior wings 21 through the medium of which the member 12 may be powerfully turned about its axis. In this connection it will be appreciated that the handle formed by the portion 8 and the wood sections 10 and 11 may beheld by an operator in one hand, whiie with his other hand the operator turns the inember 12 about its axis for the adjustment of the jaw 1 relative to the body aw 5. 1 By virtue of the spaced longitudinal bars 7, comprised in the wrench body, and the wood sections 10 and 11 carried by the said body, it will be appreciated that the wrench is provided with a convenient handle or hand grasp and that the shank 2 is adequately housed as is also the adjusting member 12, and this without making the wrench heavy and without detracting from the strength and durability of the wrench.

' It will also be appreciated from the foregoing that; by virtue of their character, the severalf parts of. the wrench may be easily produced, and that the said parts may be readily assembled and secured in relative working pnsiti om with the result that the whole may be produced at small ostrefen to. the sections 10 and 11 as ben g or wood, and, I prefer to employ sections 10 and .11 I would have it understood that within the purview of my i yention the sections 10 and 11 may be made o fiberor of other appropriate material'whieh is lighter than metal, and is at the same time capable of withstanding the rough. usage. to wdiich wrenches are ordinarayii iee e I ,lhaveentered into, a detailed description of theconstruction an d relative arrangement of parts embraced'in thepresent and preferred emb odimentjof my invention in order to ima, fulhclearg andfefxact understanding a the said embodiment, I do not desire, however, tobe understood asllimiting myself to thpregi'se eonstnuction disclosed, my invention being defined by my appended claim within the scope of which modifications may be made without departure from my invention.

Having thus described the invention, what I claim is:

A wrench consisting essentially of a sliding jaw having an integral shank provided atits rear end with a reduced and threaded portion, a body including a jaw with a longitudinal passage therein through which said shank extends, longitudinal spaced bars extending rearwardly from last named jaw and provided with rear internally recessed portions, and an intermediate portionjoining thebars immediately in front of said recesses and extending laterally in opposite directions from the planeoi the bars and having a longitudinal passage through it, sections of material different from that of the body, arranged in front and rear of the laterally extending parts of the intermediate portion of the body and, abutting, against and arranged flush with said latenal, parts and connected to opposite sides ofthe longitudinal bars, and an adjusting member journaled in the longitudinal bars of the body and in the rear sections at material different from that of the body and extending rear? wardly beyond the longitudinal bars and said sections, and havingafiange at its inner end disposed inv the said recesses of the body bars and also havinga threaded portion receiving and engaging the thread on the shank.

In testimony whereof I, aflix my signature.
